Title: Apparatus for suppressing jamming waves
Inventor: YOSHIYAMA HIROSHI
IPC: G01S13/44
Filed: 1994-04-05
Abstract: PURPOSE:To reduce a side-lobe judgement-impossible region by installing in search-threshold-factor output means which adds a threshold factor to an amplitude comparison circuit and changing the value of the factor according to every beam deflection angle, within a range which satisfies a required beam width in the search of a target. CONSTITUTION:A search-threshold-factor output circuit 13 sets and outputs a Ksrc as the optimum value of a K in the search of a target regarding a threshold factor for an amplitude comparison circuit 11 from the beam-deflection-angle signal of an output from an angle detection circuit 8. Then, when a side-lobe judgement-impossible region (region of SIGMA pattern > DELTA pattern) exists due to the degradation of an antenna pattern, the search threshold factor Ksrc times the DELTA pattern (Ksrc.DELTA pattern) and the amplitude value of the SIGMA pattern are compared by the amplitude comparison circuit 11. Thereby, a side-lobe can be judged, the side-lobe judgement-impossible region is reduced, and the removale accuracy of jamming waves can be enhanced.

Abstract: PURPOSE: To uniformly distribute the teeth loads of three gears of the transmission to increase the reliability on the transmission, by coupling a sun gear to an input shaft, a stationary internal gear to a casing, and a rotary internal gear to an output shaft, by means of a gear coupling mechanism.  
     CONSTITUTION: The sun gear 2 is coupled to the input shaft 1 by means of a coupling mechanism consisting of external crown gear 1c formed at the small diameter part of the shaft 1 and an internal gear 2a carved on the inner peripheral surface of the gear 2, and the gear 2a meshes swingably with the external gear 1c. Further, the stationary internal gear 20 is coupled to the casing 36 by means of a gear coupling mechanism consisting of an external crown gear 20a carved on the outer peripheral surface of the gear 20 and an internal gear 21 meshing  with the external gear 20a, and a rotary internal gear 25 is coupled to an output shaft 29 by means of a gear coupling mechanism consisting of internal gear 25 and external crown gear 26 formed on the outer peripheral surface of a coupling member 26, and external gear 26a meshes swingably with one-ends of the internal gear 25. By this procedure, since respective gear 2, 20 and 25 can be displaced in a diametral direction in predetermined quantities, the tooth loads are uniformly distributed to respective gears, and hence it becomes unnecessary to work component prats with high precision.

IPC: G05D16/00
Filed: 1998-03-18
Abstract: PROBLEM TO BE SOLVED: To use a pressure reducing valve for other applications except for reducing and outputting an inlet side pressure by outputting pressure oil to a signal output port provided in a valve itself in reducing pressure or not reducing pressure. SOLUTION: When an operation valve 10 is in feeding positions B, C, discharge pressure oil of a hydraulic pump 1 flows into an actuator 15 via ports 4, 5 of a pressure reducing valve 3 and a port of the operation valve 10 to actuate it in one direction. Then, the output-side pressure of the pressure reducing valve 3 is lower than the set pressure and the pressure reducing valve is in a first position by a spring 8 so that the pressure oil is outputted to a signal output port 7. When the actuator 15 is actuated in the one direction to the stroke end, the output-side pressure of the pressure reducing valve 3 is raised to be a set pressure so that the pressure reducing valve is in a second position and stops outputting the pressure oil to the signal output port, 7.  A pressure oil detecting means 18 can thus detect that the operation valve 10 is in the feeding positions B, C and that the actuator 15 is actuated to the stroke end.

Filed: 1999-02-09
Abstract: PROBLEM TO BE SOLVED: To provide a heat generating wire which is a combination of a copper wire and a iron wire and heats a wide area at a low temperature with small power. SOLUTION: This method relates to a heat generating wire heating a wide area. For example, a copper wire 1 of 0.5 mm 10 m long is combined with an iron wire 2 of 0.5 mm 10 m long to make a heat generating wire. Applying a voltage to the wire, heating is generated responsive to the voltage. At this time, this wire has heat accumulation, thereby heat can be kept even if power is interrupted because conductivity and thermal conductivity of copper and iron are different. Furthermore, heat keeping time can be made long by increasing the number of the iron wire. And when a wide area is heated for a long time, power consumption can be reduced.
